Nuclear Technology is the technologies that involve nuclear reaction. Such reactions can generate tremendous amounts of energy. There are two types of Nuclear reactions – Nuclear fusion and Nuclear fission. Fusion generally involves Hydrogen. It is the same mechanism by which the sun produces such tremendous amounts of energy. Applications of Nuclear Technologies: Agriculture: Insect…
A satellite is an object that orbits a larger object, most commonly a celestial body. It can either be a natural satellite or an artificial satellite: Natural satellites are Objects that orbit a larger object in space naturally, such as the moon orbiting Earth or Earth orbiting the sun. Artificial satellites are Objects that are…
Rockets are vehicles that use external combustion engines (Jet propulsion) to accelerate without using any surrounding air. These work by generating an impulse by the high-speed ejection of the fuel mass. Apogee & Perigee: Types of Orbits: Posigrade: Along the motion of the earth. Retrograde: Opposite to the movement direction of the earth. Low Earth…
Biotechnology refers to the technology sector that utilises biological systems, living organisms or enzymes or parts from the organisms to produce products and processes useful to humans. It essentially involves the integration of natural sciences and engineering sciences to achieve the application of organisms and parts thereof for products and services. Defining Biotechnology In today’s…
This chapter covers various types of communicable diseases that we find commonly in India and often have an adverse socio-economic impact on society. Zoonotic diseases Zoonotic diseases are those which Spread between humans and animals. In recent times, man-animal interaction has increased due to habitat destruction, increase in population and mobility. This has increased the…
Diseases where microbes are the immediate causes. This is because microbes can spread rapidly in the community. Infectious agents: Mostly microbes or micro-organisms such as bacteria, fungi, etc. have the ability to act as infectious agents. Not all microbes are harmful to us. Pathogens are microbes harmful to humans, plants and animals. Virus: Common cold,…
Health refers to the state of being well enough to function well physically, mentally and socially. Health is a relative term: for a flute player, having enough breathing capacity and being in good mental health to play flute must be healthy. Such situations may lead to an unhealthy life. It basically depends on the environment:…
Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin and contains essential nutrients such as carbohydrates, fats, proteins, vitamins, or minerals. Nutrient: It is a substance that provides nourishment essential for the maintenance of life and growth. In other words, these are components of…
The study of nuclei involves understanding the structure and behaviour of atomic nuclei, which are at the heart of an atom. The nucleus contains protons and neutrons, bound together by a force called the nuclear force. ‘ Nuclear physics explores phenomena like radioactivity, nuclear reactions, and the energy released in nuclear processes. It also plays…
The study of atoms leads to understanding the structure and behaviour of matter at the microscopic level. Atoms are the basic units of elements, consisting of a central nucleus surrounded by electrons. The concept of atomic structure was developed over centuries, with key contributions from scientists such as Rutherford, Bohr, and de Broglie. Quantum mechanics…
